ARMOR PROTECTOR FOR PNEUMATIC TIRES.

Application filed January 2, 1923, Serial No. 610,178.

To all whom it may concern:

Be it known that I, SANDOR J. SoL'rnsz, a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented a new and useful Improvement in Armor Protectors for Pneumatic Tires, of which the following is a description.

This invention has reference to pneumatic tires for automobiles and particularly relates to armor or protectors for the inner tube and for the shoe, case, or cover, and to a combination of elements and parts which cooperate to protect the inner tube from punctures, to prevent blow-outs, to rein force the shoe, case, or cover, and to add strength and rigidity to the latter.

Among the objects of my invention may be noted the following: to provide a reinforce for the shoe or cover of a pneumatic I tire which will give strength, rigidity, firmness and durability to the shoe; to provide an armor adapted for use with and to be incorporated in a shoe or cover for pneumatic tires which will reinforce the shoev and also the pneumatic tube, and will prevent blow outs, punctures and injuries of all nature to the inner tube; to provide an armor or protecting medium for the inner tube and for the shoe or cover which is strong, durable, flexible and impenetrable; and to provide a combination of elements constituting a means for reinforcing the inner tube and the shoe, operating as a protector for both the inner tube and the shoe and having all the virtues and advantages set forth in the foregoing. 1

With the above objects in view and others which will be detailed during the course of this description, my invention consists in the parts, features, elements and combinations thereof hereinafter described and claimed.

In order that my invention may be clearly understood, I have provided drawings wherein: V

Figure 1 is a bottom plan view of a section of an armor or protecting medium for use in combination with automobile shoes and pneumatic tires embodying my invention, the View showing'a form of my invention which is efficient;

Figure 4 is a plan of one of the bottom armor disks showing the details thereof;

Figure 5 is a plan of one of the top armor disks showing the details thereof; I

Figure 6 is a perspective view of one of the links employed to connect the top and bottom armor disks; i Figure 7 is a transverse section of shoe illustrating the details of construction with my armor or protecting medium embodied therein and also illustrating the method of lncorporating the armor; and

Figure 8 is a plan View of a portion of the shoe out vertically in different places and stripped so as to show the various members of the shoe and the relation and interaction of said members.

Referring to the drawings, the numeral 1 l the top, and the bottom disks 1 and 7 are made concavo-convex or dished.

A-connecting device, or link, for a series of bottom disks and a top disk is shown in Figure 6, and consists of a member having four legs 9 at a right-angle to each other in the center of which is disposed a tubular sleeve 10 projecting at a right-angle to the surface of the link. The link is preferably made of a single piece of material stamped out of sheet metal, and the central tubular member is preferably struck up from the center of the link from the material con-' stituting the central portion thereof.

In Figure 1, which shows a plurality of the disks 1 and 7 secured together to form a sheet of protecting armor, the legs of the links are shown hooked to the adjacent four disks by passing the ends of the legs 9 through adjacent apertures 6 in the disks 1 and bending them over in circular form. into contact with their own bottom surface.

This makes a linkage between every four adjacent disks which is loose and flexible and very" strong. The entirebottom of the" armor is composed of disks connected together by the links, as clearly shown in Figures 1 and 3. At the marginal edges of the bottom layer of the armor, narrow strips of metal 11 are passed through the marginal apertures 6 of the disks 1 and bent over so as to flexibly connect the strips to the disks.

The free ends of the strips 11, which are termed anchors, are, as shown in Figure 7, laid in the longitudinal margins of the shoe. under the beading 12 thereof. This will be more fully explained hereinafter. In constructing the armor, after the'disks 1 of the bottom layer have been linked together as required, the disks 7 of the top layer are secured in place upon the disks of the bottom layer by passing the tubular member 10 of the links through the central apertures 8 in the disks 7, and spreading the ends of the tubes to constitute a head 13 and thus rivet the top disks to the links, so as to hold thetop disks in proper relation to the bottom disks. In making this connection,

the concave side of the top disks is opposed to the concave side of the bottom disks, and

while the top disks 7 are prevented from slipping off the tubes 10 by the heads 13 thereof, said disks can slide and rock on the tubes to accommodate themselves to movements of the armor in use. The connection of the disks 7 to the tubes 10 is, therefore, loose. Thus, when the armor iscompleted, both surfaces will be composed'of units consisting of oppositely disposed overlapping disks linked together in one series and riveted in another series to the first series; and it is to be noted that the tubular rivet 1O passing throughthe'top series'of disks 7 does not hold the top series of disks rigidly incontact with the lower series of disks 1. On the contrar', the disks of the top series have a slight sliding and rocking movement on the rivetsfand away from the circumference of the opposing disks of the bottom' series. 7 H

As will be seen upon reference to Figure 2, the top series ofdisks 7 are arranged,

closely together so that their circumferences practically touch without overlapping each other. Nevertheless, at this point, during the operation of the shoe and the flexing of the armor, there is a slight separation or gap between the adjacent edges of the said disks 7. This gap isclosed so as to prevent the intrusion of any pointed or foreign element by the lugs 2 and 3, which overlap the edges of adjacent disks land close the gap between a'djacent' disks 7. The lugs 2 and 8, during the use of the shoe'andthe flexing oftheiarmor, have aslight sliding move t' rfadiaent i ks lend, e at e y Gene ati disks and e o s nd. 5 of the; disks 1 interact with the lugs 2 and 3 in a manner such that the walls. er the were will arar he disks 1 from shift reinforcing canvas 15.

ing too much laterally relatively to the links, the walls of the notches 'co'operatingwith the walls of the lugs tomaintain thedisks 1 in proper cooperative relation. Thus the disks 1, while having an abundance of flexibility relatively to each other and relatively to the links and the, disks 7, are prevented from shifting either axially or in the direction of their circumference by the lugs 2, 3 and notches 4t, 5 to eliminate any ossibility of strain being brought upon the if. links. The loos'e connection of the links to the disks 1 and the loose sliding connection of the links tothe disks 7 provide fora maximum of flexibilit in practically every angular direction and enable the armor or protecting medium to flex universally so as of rubber gum or cement, "and the said armor extends circumferentially of the shoe and from bead'to bead thereof or edge to edge thereof throughout practically the The protecting entire area of the sliee. I medium is secured in place along the'edges of the shoe by turning the anchors 11 under the outer mar inal'broau edge of the solidi- .fie'd material constituting the bead 12, the

anchoring means bein'gth'us located between V the body of the shoe the bead and the naterial of the bead, so that when the material of the head is secured in place within the edge of the. material of the shoe it securely fastensthe' anchoring links in place in bent condition, thus provldmg a strong, mar ginal, interlocking securing means forthe armor or protecting medium, which prevents the armor from shifting, sliding or b'emg drawn or dragged out of place. This avoids frictional heating and any 'possibilityfof distortion of the armor within the shoe;

gs of the As shown in Figures? and 8, the shoe is made up "of the rubber tread 14;, to the inner surface of which is seem-ed athin piece of 7 To the reinforci it, canvas 5. layer of rubber gum 16 is applied,

followed by a heavy piece of canvas 17, to"

which another heavy coating or layer of rubber gum 18'is applied. On the layer of 3 medium is laid with the top composed the disks '7 extending outwardly or toward rubber "gum 18 the "armor or protectin the-circumference of the shoe. Nesta heavy layer of rubberfgurn 19; is applied to the armorpr prbtectingn'iedium and th enam other heavy layer of canvas constituting the inner lining of the shoe. The anchoring links 11 along the edges of the armor are, as before stated, turned under the beads 12, and, in the regular course of vulcanization of the constituent parts of the shoe, are caused to firmly adhere together. During the process of vulcanization, the two layers 18 and'l9 of rubber applied to the opposite sioes of the armor become fused, so to speak, with each other and completely saturate and embed the armor therein, the armor in this sense practically floating or being suspended in the double thickness or layers of rubber.

The substantial character of the armor or protecting medium constitutes a stron and durable reinforce for the shoe and a so a reinforce, protector and support for the pneumatic tube held within the shoe. By intervening the substantial armor or protecting medium in the body of the shoe between the tread thereof and the inner tube, blow-outs are prevented, undue distention of the inner tube is prevented, the inner tube is rendered puncture-proof, the shoe is stabilized, rendered strong, durable and much more rigid and capable of withstanding strains, and the characteristics of the armor are such that no sharp instrument such as nails, knives, glass, etc., can penetrate the shoe beyond the armor. There fore. anything which penetrates the shoe cannot possibly reach the inner tube, and, regardless of the hole made by the penetration, whether it be a hole, slit or a great gash, no blowout, nor puncture of the inner tube can occur, nor can leakage take place, since the heavy compound layer 18, i9 of rubber constitutes practically a second inner tube through which the air cannot penetrate.

Having thus described my invention, what I claim and desire to secure by Letters Patent is:

1. An armor or protecting medium for automobile tires comprising a plurality of layers of concavo-convex disks, one layer of the disks being flexibly linked together and another layer of disks being flexibly riveted to the disks of the first layer, said protecting medium having along its longitudinal edges anchoring devices adapted to be secured to the shoe substantially as described.
